I still have a leak in the rear...very disappointing! Taillights are dry and it is not leaking at the running lights. I've checked the roof vents, etc. again and they look good. The only thing left is the awning rail. After that, I give up!

Dean, sure you've checked windows for leaks at rear of motorhome, is there a possibility if the aluminum rear cap wraps for possible leak? Try temporary fix by applying the Vulkem caulk along rivet sections. May not be 'pretty' but would rule out the roof.
Good Luck, Derek

I picked up the third section of hose and finished off the duct replacement. There should be no more complaints of not enough A/C from the passenger . And no more frosted window on those cold wet mornings out on the road! It takes about 15 feet of duct to redo the A/C and defroster ducts.

I feel your pain Dean.
Yesterday and last night, We had the same deluge that passed over you.
I went over there yesterday afternoon between showers and was disapointed to find a little patch in the same LH rear corner under the bed. Better than it was, but still not right.
Poking about with a dry tissue to ID the actual area, its clearly dripping down between the skins now.
Also found signs of a leak where the gas filler is, but I had not sealed that yet.

In a previous life, my moho was involved in an accident that did a lot of damage to the right a-pillar, side window, and roof. I purchased it in a semi repaired state. The floor was saturated, and the whole area leaked at every joint. I had to remove the side window, and do a lot of refitting, re-seaming, and re-sealing of panels to get it squared away. I also had the significant advantage of doing my leak testing with the interior panels removed.

I was amazed at how much water could flow past just a single loose rivet. The awning track could be the culprit since that connection is routinely stressed whenever the awning is deployed. The awning assembly also has some significant weight and stiffness to it, and probably resists the independent flexing of the moho's frame and skin during driving, or leveling, or jacking.

Obviously, the real challenge is finding the leak. Along the lines of what Derek suggested, I used lengths of duct tape, and butyl tape as temporary "flashing" to try to eliminate potential problem spots. Sheets of "dyna-mat" acoustic insulation were very handy for this. I also found that leak testing with a hose on a dry sunny day was easier than trying to sort it out in the rain when you have no control over the water source (besides, watching your coach leak in the rain is just plain depressing). I generally tested from the bottom, and gradually moved the water source upward.

Is there any possibility that you are leaking from a vent or rooftop A/C unit that is some distance away from where the water is appearing? Is the coach always parked in the same place, or at the same slope when the leak appears? How about the fuel filler door? Overhead marker lights?

Visited the 82 24' Ste P yesterday and it was leaking from the passenger side windshield......wouldn't have known except for the rain storm....and being there that day....not huge leak so would have dried before I went there again...so the windshield needs to be resealed......

We had a huge leak on our 68 28' Ambassador this past summer in Ft. Collins, Colorado. It was leaking above the forward curbside vista view window...it turned out to be from the awning rail.....not easy to fix as there was an awning there but it took a popsicle stick to poke sealant up under the awning into the screw hole that was open...

We don't have an awning on the MH but you can bet, we will have it looked at real hard before we install one.....paula

We had a rivet failure that drove me nuts for years, because it would only leak when the coach was at a certain angle, With a tall ladder, I finally found it and used Parbond to seal it. The thing that really rang my bell, is the leak had prolly happened from day one, and the P.O. had tried to caulk it from the inside! The awnings were generally installed post-factory, hence the problems with leaks. I cleaned the area where the awnings screwed to the roof and used Vulkem (on a warm day). I've told a number of people who admired Airstreams, "all coaches leak, just like boats."

I replaced the nylon guides on the two sliding doors over the refrig today. I also replaced the right side backup can with a new one from my spares...wires and socket were corroded on the old one. Didn't do any more today on the roof leak, but at least the taillight and running light lenses are clean!

I took a look under the "hatch" today (the cutout in the bedroom floor just over the fuel tank. All looks good! It's dry, no gas smell and hoses and clamps look great! Well, one less thing to deal with right now

I replaced the water temp sender with a second one today. The first one I got at Autozone purely out of convenience. It did not work. Second one I got at Napa purely out of convenience. I don't really care for Napa. This one works and it even looked like the original.

Ah, more ways to distract drivers, mobile phones, texting and things of this nature are killing us bikers... Literally. I'm not trying to pick any fights here and I'm not trying to get personal with you either. Seeing things like this just scares the S#@T out of me. Please, please don't play with your iPad while you are driving. I have personally nearly been road kill from people texting while driving. I've come so close to death I could see their finger's typing as they were coming at me in a curve on the wrong side of the road. You gotta wonder who they are texting that is so important it's worth risking killing yourself and others over. Besides, if you crash your Airstream then Dadstoy will be no more, even if you don't hurt a soul. That would be sad enough. Okay, I'll climb down off my apple crate. I hope we can still be friends Be safe out there.
